Holy moly. Well done

I received my carts today, and just want to show my appreciation for the efforts that have gone into getting this project over the line.

This project looks amazing.

I'll be interested in an MVS one.

Good job there! So even after probing the Z80, the RAM was still suspected to be at fault? It goes to show... I need to repair a board which plays sound fine on boot but plays random SFX and music. I don't have the skills to probe the board so will change the Z80 for a Z80a.

I've got an A board behaving like this. I believe it's to do with the Q sound, perhaps it's not making a proper connection between A and B.

I think it is a compatibility issue. The A board I was having issues with, works totally fine a legit SF2CE.

So I've changed the resistors at R46 and R47, the sound still cuts out.

Dark soft multi works with new a board. Mercs works first go. 89626a-4 10mhz board.

Ok, so my genuine SF2CE stack has turned up. I’ve taken readings of R46 and R47 and it gives similar readings. Plugged known working B and C board into my CPS1.5 board - no sound issues. SF2CE works a charm. As far as I’m concerned, my A board got repaired with the capacitors. I will test the...

So it turns out after the recap, I get beefier sound, but the BGM still cuts out for me. On mercs, it’s always within 10 seconds. On other games it’s random. I’ve read on another forum that it could be the YM3012, z80 chip or the OKI or the sound crystal. So… someone mentioned on another...

I forgot to mention that all the q sound games worked without issue for me too.

It sounds the same behaviour, it was driving me mad! I even ordered an expensive genuine a board to test SF2CE but looks like it will be surplus when it arrives. If your board is an Ali board, which I reckon it is, recap the board and go from there. Test on your blast city. The crust most...

Hey, so I've recapped the board, and have it running stable at 4.9v. WOW, I'm hearing SFX I never did before. Thanks everyone who replied.

I Oh wow, this was what I was looking for. How much was the CPO?
